We propose and demonstrate a method to increase the momentum separation between the arms of an atom interferometer and thus its area and measurement precision, by using Bloch oscillations (BOs) in an excited band of a pulsed optical standing-wave lattice. Using excited bands allows us to operate at particular “magic” depths, where high momentum-transfer efficiency (>99.4% per ¯hk, where ¯hk is the photon momentum) is maintained while minimizing the lattice-induced phase fluctuations (
